April 1st is April Fool's Day, with a tradition of practical jokes. Instead, here's a nice collection of Musical Instrument Jokes to lighten your day.
For some light reading, try Victor Borge's My Favorite Comedies in Music or other books of musical anecdotes. You'll find them at the Polley Music Library.
Or, how about some novelty songs. We may have no bananas, but we do have a lovely bunch of coconuts along with some shoo-fly pie and, of course, the ice cream we all scream for in Gilly Gilly Ossenfeffer Katzenellen Bogen by the Sea. The Polley Library has several novelty songbooks.
Have a wonderful light-hearted day.
